If only those two die, will I have the face of a king?

King Sejong wanted to give his princes various opportunities and responsibilities.
First, the eldest prince, Crown Prince Munjong, had to do everything unconditionally.
The second, Grand Prince Suyang, and the third, Grand Prince Anpyeong, were also heavily utilized.
Sejong had particularly high expectations for the fifth, Grand Prince Gwangpyeong.
He even involved him in the creation of Hangeul at a young age, but he died prematurely at 19.
The following year, the seventh son, Grand Prince Pyeongwon, died at 18.
Queen Soheon (Lady Shim) gave birth to 8 sons and 2 daughters and raised almost all of them to adulthood.
Given the child mortality rates of that era, this is an almost impossible record.
After losing two grown sons in succession, the mother could not endure the grief and passed away.
And her husband, King Sejong the Great, passed away in 1450, about three years later.
Fortunately, Grandmother Queen Soheon and Grandfather Sejong
were able to witness the birth and some of the upbringing of the only legitimate grandson, King Danjong.
The problem was that after Danjong was born, the Queen Consort (the Crown Princess, later Queen Hyeondeok)
died of postpartum complications the very next day.
Due to King Sejong's deteriorating health, including blindness and diabetes, Munjong
served as regent for nearly 10 years. After losing his wife, he observed a 3-year mourning period for his mother, and once that ended, a 3-year mourning period for his father...
Munjong, a principled man filled with filial piety, saw his health completely break down.
There is a story in unofficial histories.
It is said that Sejong, who loved meat so much, secretly ate meat while mourning his father, King Taejong.
Since meat is forbidden during mourning, how is Confucianism and Neo-Confucianism any different from Islamic fundamentalism?
Without a grandmother to act as regent or a mother to guide him, Munjong passed away,
and Danjong ascended the throne at the young age of 11.
Before his death, Munjong entrusted his young nephew to his younger brothers, Grand Prince Suyang, Grand Prince Anpyeong, and Grand Prince Geumseong, and instead of a formal guardian, he requested Kim Jong-seo and Hwangbo In to look after him.
Danjong received royal training from the age of 4.
He was also taught by his grandfather, Sejong, whenever possible.
He was showered with affection from his grandmother, Queen Soheon,
and received immense love from his sister, Princess Gyeonghye, who was six years his senior.
Above all, Lady Yang (Hye-bin), a concubine of King Sejong, took full charge of his upbringing and breastfed him.
The Gyeyu Jeongnan? You might as well call it a "fried egg" coup (a pun on 'Jeongnan' meaning disturbance and 'Yujeongran' meaning fried egg).
I believe it is the only coup in Joseon history that lacked any legitimate justification.
After the coup, Suyang claimed that Grand Prince Anpyeong had conspired with Kim Jong-seo and Hwangbo In
to commit treason and make Anpyeong the king.
Thus, Suyang's uprising succeeded; he assassinated Kim Jong-seo and Hwangbo In,
and used Han Myeong-hoe's "slaughter list" to kill everyone on it.
He exiled his own brother Anpyeong to Ganghwa and eventually forced him to commit suicide.
Let's say that part is as it is.
Some of the Six Martyred Ministers, such as Seong Sam-mun, criticized Kim Jong-seo's unilateral actions.
But if Suyang truly had such pure intentions, why did he receive the throne through "abdication"?
The Six Martyred Ministers believed that it was actually a dark, treasonous ambition.
This is a reasonable inference, whether thought by the public or a third party.
Is there any record in thousands of years of history of someone receiving an abdication and being spared?
There are records of conquering other nations and sparing them, but there is no record of
receiving an abdication and being spared within the same country.
From the Gyeyu Jeongnan onward, Danjong was destined to die.
It is useless to blame the complacency of Kim Jong-seo and Hwangbo In, who held the power.
Jeong Mong-ju and Jeong Do-jeon suffered similar fates.
Even Jeong Mong-ju, who held power, did not know his disciple Yi Bang-won would kill him.
Even Jeong Do-jeon did not know that while having a banquet at his remaining house without guards,
his head would be cut off by Yi Bang-won, whom he called "uncle."
At least Yi Bang-won had sufficient justification compared to Suyang.
Why did he make his youngest brother, Bangseok, the Crown Prince, despite him having zero merit in founding the dynasty?
It seems Grand Prince Suyang had a complex regarding his older brother Munjong and his younger brother Anpyeong.
In fact, wasn't he less talented than Munjong and Anpyeong?
Here is why I say Grand Prince Suyang was not human:
1. He exploited the deaths of his father and brother.
2. He assassinated people unconditionally without arrest or interrogation.
3. He coerced his nephew into a forced abdication.
4. He deposed the abdicated King and demoted him to Prince Noseon.
5. He committed the ultimate immorality by killing his own brother Anpyeong, Geumseong, and his half-siblings.
6. He exhumed the royal tomb where Munjong had been buried with someone else 10 years prior and threw his sister-in-law's coffin into the West Sea.
7. He ultimately killed his nephew and prevented his body from being properly recovered.
8. He killed Lady Yang (Hye-bin) and her children, the very woman who had raised Danjong at King Sejong's request.
9. While his grandfather, King Taejong (Yi Bang-won), had guarded against powerful officials and in-laws by nearly wiping out the Yeoheung Min and Cheongsong Shim clans,
Suyang raised the very powerful officials and merit subjects of the Gyeyu Jeongnan—Han Myeong-hoe, Hong Seong-yun, Shin Suk-ju, Jeong In-ji—as well as the corrupt official Yu Ja-gwang.
10. Through his direct lineage, he produced useless rulers like Yeonsangun, Seonjo, and Injo.
Joseon merely lingered on; in reality, it ended here.
